BOTTLE-CA1.

Application filed May 26, 1913.

To all whom it may concern:

Be it known that 1, ROBERT Mo'r'sn BENorr AARONSON, a citizen of theFrench Republic, residing at Paris, in France, have invented certain newand useful Improvements in Bottle-Caps, of which the following is aspecification, reference being had therein to the accompanying drawing.

This invention has reference to an improved bottle cap tobe applied toany kind of receptacles whatsoever, such as bottles, jars, pots and thelike, so as to permit of unstoppering the receptacle by hand without theassistance of any tool or instrument and of restoppering it hermeticallywith the same facility after extracting a portion of its contents.

I shall now describe my invention with reference to the accompanyingdrawing showing one form of construction by way of example, in which:

Figure 1 shows separately the various.

parts composing the cap. A is a metal capsule, the borders of which arethreaded so as to screw on to C. B is a Washer contained in the capsuleA. C is the metal socket threaded at its upper portion for receiving thecapsule A. D is a split ring of square metal wire. E is a sealing bandfor assuring the inviolability of the contents of the receptacle towhich the system is applied. Fig. 2 shows in section one method offitting the system to a special bottle with a circular groove on theupper portion of the neck. Fig. 3 shows another method of fastening thesystem to an ordinary bottle, that is to say without groove, by means ofthe split ring D provided for this purpose. Fig. 4 is a top plan View ofthe sealing band.

This system of stoppering is employed in the following manner: Beforestoppering the receptacle the capsule A with the washer B is screwed tothe threaded portion of the socket C so as to form one piece, then bymeans of a special machine the socket is firmly fitted to the neck G ofthe receptacle by means of its lower portion by pressing the metal intothe groove H provided for this purpose in the receptacle speciallyconstructed for fitting with this stoppering system such as shown inFig. 2; or by means of a metal ring or binding compressing the socketagainst the walls of the receptacle or otherwise. Fig. 2 also shows thespecial form of neck G of the bottle with its circular groove I-I.

Specification of Letters Patent.

Patented Feb. 29, 1916.

Serial No. 770,008.

For ordinary bottles (Fig. 3), that is to say those that have not beenconstructed specially and consequently are not provided with a groove, asplit ring of square metal wire is employed which is placed on the neckneck. The ring D thus arranged on the neckv of the bottle is for thepurpose of offering a sufiicient and regular projection so as to be ableto tighten up on it the lower portion of the socket C which could not bedone otherwise on account of the irregularity of the bottles which arenot specially constructed.

In order to guarantee the contents of the receptacle a sealing band Ewhich is removed by tearing and made of metal or goldbeater skin orother suitable material is placed on the capsule A in a diametraldirection. Furthermore its two ends are folded under the lower edge ofthe socket, so that this sealing band is held by the clamping of thestoppering system on the receptacle (see plan, Fig. 4). This band hastwo notches F (one on each edge) slightly passing beyond the axis X soas to form a weak point which permits of it being torn when desired.

The system if applied to bottles, ars, pots or the like by one of themeans referred to above, it is evident that for unstoppering thereceptacle in order to extract a portion of its contents no specialinstrument will be necessary. It suflices to unscrew the capsule A whichcarries with it the washer B, this unscrewing movement exerting atraction effort on the band E which is broken at the notches F and whichafter being completely torn permits of wholly withdrawing the capsule A.In order to restopper the receptacle after use for the purpose ofpreserving its contents in good condition by excluding the surroundingair, the above operation is. reversed, that is to say the capsule A isscrewed back-on the socket C, the washer B again presses on the neck ofthe receptacle which it hermetically closes. These two op erations arerepeated as often as desired, as

long as the receptacle is notempty. By

' means of this system'the contents do not deteriorate or alter and iffor example the bottle containsmineral water or beer the liquids retaintheir gases up to 'the end.

. Thethreading ofthe capsule andthat ofthe socket may be substituted by.any other fastening system such as for example a bayonetjoin.

Having now described my invention and set forth its merits, what Iclaim, and desire to secure by Letters Patent is:

' An improved stopper for bottles, jars and the like comprising incombination, a

screw threaded capcontaining a washer, a sealing band of metal providedwith two notches on each border passing beyond the longitudinal axis ofthe band, and adapted to be automaticallytorn when the cap is unscrewedfor .unstoppering the receptacle,

. substantially as described. a

- In testimony whereof I affix my Witnesses:
